'Place the letter of th item in Column II on th line before its best match in Column I'
Column I:
37. moderator
38. coolant
39. control rod
40. critical mass
Column II:
a. removes heat from reactor
b. slows neutrons produced by fission
c. limits number of free neutrons
d. amount of uranium needed to sustain a chain reaction
I reallyy need help with this!
Thanks

To match the items in Column I with their best matches in Column II, follow these steps:
1. Review the items in Column I and Column II.
2. Assess the statements in Column II and determine which statement best describes the item in Column I.
3. Place the letter of the item in Column II on the line before its best match in Column I.
Matching the items, the correct corresponding letters for Column I are:
37. moderator: a. removes heat from reactor
38. coolant: a. removes heat from reactor
39. control rod: b. slows neutrons produced by fission
40. critical mass: d. amount of uranium needed to sustain a chain reaction
Place the letters as follows:
37. moderator - a
38. coolant - a
39. control rod - b
40. critical mass - d
Hope this helps you!
To place the letter of each item in Column II before its best match in Column I, you need to match the descriptions in Column II with the corresponding items in Column I. Here's how you can do it:
1. Read through the descriptions in Column II and understand their meanings.
2. Start with item 37 in Column I, which is "moderator." Look at the descriptions in Column II and find the one that best matches the purpose or function of a moderator.
- Description a. "removes heat from the reactor" does not match the purpose of a moderator.
- Description b. "slows neutrons produced by fission" matches the purpose of a moderator.
- Description c. "limits the number of free neutrons" does not match the purpose of a moderator.
- Description d. "amount of uranium needed to sustain a chain reaction" does not match the purpose of a moderator.
So, the best match for "moderator" in Column II is b. Slows neutrons produced by fission.
3. Repeat the process for the remaining items in Column I:
- Item 38: "coolant" matches with Description a. Removes heat from the reactor.
- Item 39: "control rod" matches with Description c. Limits the number of free neutrons.
- Item 40: "critical mass" matches with Description d. Amount of uranium needed to sustain a chain reaction.
Once you have matched each item in Column I with the corresponding description in Column II, you can place the letter of each item from Column II on the line before its best match in Column I.
Final Placement:
- 37. b. moderator
- 38. a. coolant
- 39. c. control rod
- 40. d. critical mass
I hope this helps! Let me know if you have any further questions.
